Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional conveying devices in combination weighing apparatuses face challenges in efficiently adjusting the conveying amount of articles, as existing technologies require multiple restricting plates of different shapes and materials, leading to high costs and reduced operating efficiency.
Innovation Solution
A conveying device with a variable-angle restricting plate that can be adjusted to control the flow of articles, eliminating the need for multiple plates by rotating and positioning the plate to alter the gap between the trough and the restricting plate, allowing for precise adjustment of the conveying amount.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If passage width restricting members with different shapes and materials are exchanged to adjust conveying amount, then versatility is improved, but cost increases and operating efficiency decreases
Solution Approach 1:
The restricting plate is made rotatable about a vertical axis, allowing its angle relative to the conveyance direction to be dynamically adjusted. This dynamic adjustment replaces the need for exchanging multiple static restricting plates with different shapes, enabling one plate to perform multiple adjustment functions and eliminating downtime for plate changes.
Solution Approach 2:
The conveying amount is adjusted by changing the angular parameter of the restricting plate rather than by physical exchange of components. By rotating the plate to different angles, the effective passage width is modified, providing continuous adjustability without requiring multiple discrete plates.
2Adaptability or versatility
If multiple passage width restricting members are prepared for exchange, then versatility is improved, but device complexity and cost increase
Solution Approach 1:
A single restricting plate is designed to perform multiple functions by rotating to different angles. The same plate can restrict flow at various degrees, replacing the need for multiple specialized plates. This multi-functionality reduces the number of components required and simplifies the overall device structure.
Solution Approach 2:
The restricting plate incorporates rotational capability, transforming a static component into a dynamic one. This allows one component to assume the roles of multiple static components, reducing device complexity while maintaining versatility.
3Manufacturing precision
If passage width restricting members are exchanged for all troughs, then conveying amount adjustment is improved, but time consumption increases
Solution Approach 1:
Each restricting plate can be independently rotated to the required angle without waiting for other plates to be exchanged. This dynamic adjustment capability eliminates the sequential time loss associated with exchanging plates in multiple troughs, allowing parallel or independent adjustment of each conveying device.
Solution Approach 2:
The restricting plates can be pre-set to specific angles during installation or maintenance, and then quickly adjusted during operation by simple rotation. This preliminary positioning reduces the time required for frequent adjustments during production operations.

AI summary
The object of the present invention is to provide a novel conveying device with which it is possible to easily adjust a conveying amount of articles in a trough using a restricting plate, and a combination weighing apparatus having the conveying device. A conveying device (1) to convey articles in a trough (2) has a restricting plate (4) to restrict a flow of the articles in the trough and the angle at which the restricting plate faces the articles is variable. With this configuration, there is no need to prepare a plurality of restricting plates that have different shapes and materials or to exchange such a plurality of restricting plates in the same manner as in a conventional device because the conveying amount in the trough can be adjusted merely by varying the angle at which the restricting plate faces the articles.
